NH4I will completely dissolve in ammonium and iodide ions: of which I-is neutral and NH4+ is quite a weak acid (pKa = 9.25). (The molar standard solution of NH4I will have pH approx. 4.6).
Additional Problems for practice 1. Rank each of the following compounds from the most to the least acidic: In all cases, consider the stability of conjugate base form of the acid: HA + H2O H3O + + A-a. HCO2H, HNO3, NH3 HNO3 + H2O H3O + + NO 3-N O-O O-+ N O--O O + N O-O O three resonance forms of conjugate base HCOOH + H2O H3O + + HCOO-O O-H O-O H
